Assembly features: tapped holes

[beng021228]

I'm trying to apply tapped holes to an assembly and I keep getting a "feature failed to regenerate" error. I'm relatively new to pro/e creo so I might not be using the right terms when searching for the answer. I need to put these tapped holes at the assembly level because they need to relate to locating pins that are also being placed at the assembly level. I can put the hole (sketched extrusion cut) for the pin at the assembly level just fine.


I'm using Creo elements/pro 5.0.

Thanks for any help.
